Gurunath Meiyappan and Vindoo Dara Singh have been remanded to judicial custody until June 14, a Mumbai court has ruled.
Gurunath had been in police custody since his arrest on May 24, and Vindoo since May 21.
Gurunath, a top Chennai Super Kings official and son-in-law of BCCI president N Srinivasan, was arrested by Mumbai Police on charges of cheating, forgery and fraud after being summoned to Mumbai for questioning over alleged betting and links to bookies.
Police investigations suggested that Vindoo, an actor, and Gurunath were in frequent telephonic contact. Vindoo was also seen in the Super Kings box at IPL matches.
